railsのrescue_fromの使い方

Question

railsのraiseメソッドでエラーを起こすのには成功したんですが、rescue_fromメソッドで例外処理に以降しません
下のコードのどこが間違ってますか？

class ApplicationController < ActionController::Base
    layout :set_layout
    
    puts "ApplicationControllerだよ"
    class Forbidden < ActionController::ActionControllerError; end
    class IpAddressRejected < ActionController::ActionControllerError; end
    rescue_from StandardError, with: :rescue500
    rescue_from Forbidden, with: :rescue403
    rescue_from IpAddressRejected, with: :rescue403

    private def set_layout
        if params[:controller].match(%r{\A(staff|admin|customer)/})
            Regexp.last_match[1]
            puts "set_layoutだよ"
        else
            "customer"
        end
    end

    private def rescue403(e)
        @exception = exception
        puts "rescue403だよ"
        render "errors/forbidden", status: 403
    end

    private def rescue500(e)
        puts "rescue500だよ"
        render "error/internal_server_error", status: 500
    end
end

class Admin::TopController < ApplicationController
    def index
        raise IpAddressRejected
        render action: "index"
    end
end

例外処理の中が間違ってました

private def rescue403(e)
        #@exception = exceptionではなく
        @exception = e
        #でした
        puts "rescue403だよ"
        render "errors/forbidden", status: 403
    end
